What is 40 degrees when it comes to camping? Is it a normal camping temperature, or does it cross the line into cold-weather camping? Where exactly does it fall on the seasonal camping scale?

The truth is, 40-degree weather straddles the line between the everyday and the downright chilly. While it’s comfortably above freezing, it retains an undeniable crispness in the air that can make for a cool camping experience.

When venturing out in 40-degree weather, you get both the charms of milder climates and the challenges of colder conditions. You won’t get your bones completely chilled, but a little planning is still required to keep things safe and comfy, especially at night.

Choosing the Right Camping Gear

When camping in 40 degree weather, it’s essential to have the right gear to stay warm and comfortable. Here are some tips on choosing the right camping gear for your trip.

3-Season Tent vs 4-Season Tent

When it comes to tents, there are two main types: 3-season tents and 4-season tents. 3-season tents are designed for use in spring, summer, and fall, while 4-season tents are designed for use in winter. If you’re camping in 40 degree weather, a 3-season tent should be sufficient as long as it’s well-ventilated and has a rainfly to keep you dry in case of rain or snow. But, if you want extra security, opt for a 4-season tent, which has better insulation.

Down Sleeping Bag

A down sleeping bag is an excellent choice for camping in 40-degree weather. Down is an excellent insulator, and is lightweight and compressible, making it easy to pack. Look for a sleeping bag with a temperature rating at least 20 degrees lower than the coldest temperature you expect to encounter. So, if you’re camping in 40 degree weather, look for a sleeping bag with a rating of 20 degrees or lower. This helps prevent nasty (and chilly surprises).

Sleeping Pad

A sleeping pad is essential for insulating you from the cold ground, and the ground will still be plenty cold in 40 degrees. Look for a sleeping pad with a high R-value, which measures its insulating properties. The higher the R-value, the better the insulation.

Proper Clothing for Cold Weather Camping

When camping in 40-degree weather, proper clothing is essential to staying warm and comfortable. Dressing in layers is key to regulating your body temperature and staying comfortable throughout the day. Here are some tips for layering effectively:

  • Base Layer: Your base layer should be a close-fitting layer made from a material that wicks moisture away from your skin. Merino wool is a great option for this layer, as it is warm, breathable, and moisture-wicking.
  • Middle Layer: The middle layer is what provides most of the warmth. Choose an insulating layer that is warm, but not too bulky. Fleece, down, or synthetic materials are all good options.
  • Outer Layer: Your outer layer should be windproof and waterproof to protect you from the elements. Look for a jacket and pants that are breathable, so you don’t get too sweaty.

In addition to your top and bottom layers, you’ll also need:

  • Wool Socks: Wool socks are a must-have for cold weather camping. They will keep your feet warm and dry, even if they get wet.
  • Gloves: Bring a pair of gloves to keep your hands warm. Look for gloves that are insulated and waterproof.
  • Beanie: A beanie will help keep your head warm, which is important since a lot of heat is lost through your head.
  • Breathable Clothing: It’s important to wear breathable clothing, so you don’t get too sweaty. Sweat can make you feel colder.
  • Thermals: If you’re really sensitive to the cold, consider wearing thermal underwear. They will add an extra layer of warmth and help regulate your body temperature.

Note: In 40 degrees, you may want to overpack just a bit. While you don’t want too much to carry, 40 degrees can feel very different depending on what you’re doing. When you’re hiking, for instance, 40 degrees can seem quite comfortable, and some of your layers may be too hot. When your sleeping, 40 degrees can feel considerably colder.

For this middling temp, it can be a good idea to have an extra set of mid or out-layers that are a different weight than your main set. That way you can more easily swap layers to regulate your body temp based on activity.

Setting Up Your Campsite

When camping in 40-degree weather, a proper campsite setup can make a big difference in your comfort levels and just how cold that 40 degrees feels. Follow these tips to help insulate your campsite from the elements:

Tent Preparation

When setting up your tent, choose a flat, dry surface with a ground cloth or tarp underneath to prevent moisture from seeping through the floor.


Using a rainfly is essential when camping in 40 degree weather, as it will protect you from any rain or wind that may occur during the night. Make sure to properly secure the rainfly to your tent to prevent it from blowing away in the wind.


When choosing a campsite, make sure to select an area that is sheltered from the wind as much as possible.

Preventing and Addressing Hypothermia

Hypothermia is the condition that arises when your body loses heat faster than it can produce it, leading to a concerning drop in body temperature. It’s most commonly associated with frigid environments, but it’s crucial to understand that even at 40 degrees, especially with dampness or wind, the threat remains.

The real danger with 40-degree weather is complacency. Because it doesn’t feel as brutally cold as freezing temperatures, you may fail to take the same precautions. But hypothermia is still a very real threat at 40 degrees, and staying warm and dry is paramount. Here’s how to approach this middling temperature when it comes to preventing hypothermia:

Dress Appropriately: Especially focus on keeping the extremities—head, hands, and feet—covered as they are susceptible to rapid heat loss.

Stay Vigilant: At the first hint of feeling cold, be proactive. The cold can creep in subtly in 40-degree weather. Engage in activity to generate body heat, adjust your clothing layers, or have a warm drink.

Recognize the Signs: Hypothermia in 40-degree weather might not set in as rapidly as in colder conditions, but it’s still essential to know the symptoms—shivering, confusion, slurred speech, and lack of coordination. If anyone exhibits these signs, act swiftly. Get them to a sheltered area, replace any damp clothing, and warm them with blankets, sleeping bags, or hand warmers.

Always Prioritize Safety: If someone’s condition doesn’t show signs of improvement or deteriorates, do not hesitate to cut your trip short and seek medical intervention.

While 40-degree camping is less harsh than its colder counterparts, vigilance and preparation remain vital. Equip yourself with the knowledge and gear to ensure a safe and enjoyable camping experience.

Preparing for a 40-Degree Weather Camping Trip

Embarking on a camping trip in 40-degree weather strikes a balance between a typical outdoor adventure and the challenge of a cold-weather expedition. Ensuring a safe and memorable experience still calls for thoughtful preparation. Here are some vital tips to guide your planning:

Research the Location: Prior to your adventure, become familiar with the intended camping spot. Examine the local weather forecast, keeping an eye out for any sudden changes. Knowing the lay of the land can also guide you to the optimal places for establishing camp.

Plan Ahead: Communication is key. Always relay your camping details and the estimated length of your stay to a reliable individual. If unpredicted situations arise, having someone knowledgeable about your whereabouts can be crucial.

Packing Checklists: Assess your gear meticulously before setting out. The likelihood of overlooking a crucial item is real, so curate a comprehensive checklist. This strategy ensures you’re equipped with essentials and wards off the temptation to pack redundant items.

Physical Preparation: 40-degree weather, while not bitterly cold, can still present physical challenges, especially during the nights. Prep your body in the preceding weeks with moderate exercises or walks. This conditioning will help you navigate the physicality of camping in such temperatures with greater ease.

Emergency Kit: Curate a dedicated emergency kit infused with must-have items: a whistle, flashlight, extra batteries, first-aid components, and essential contact details. In the face of unexpected scenarios, this kit could prove to be indispensable.

Stay Flexible: The outdoors, by nature, is a realm of unpredictability. Be prepared to adapt your itinerary or even shorten your journey if atmospheric conditions become unfavorable. Always place safety at the forefront of your planning, and there’s no reason your 40-degree camping trip can’t go off without a hitch.
